nonskrn` CHAIN.

.fipiiiication fiied March as, 192e. seriai no.Y s638115.

The object of this invention is to provide a new and improved type ofnon-skid chain for automobile tires.

This and other objects of this invention will be fully illustrated inthe drawing, de-

scribed in tliespecification and pointed out iii the claims at the endthereof.

In the accompanying drawing:

Figure l is a Side elevation of a portion of in a wheel and tire withtheJ non-skid chain attached thereto.

Figure 2 is a detail,perspectiveview of one of the links ofthe non-skidchain. Figure 3 is a top plan view of a portion of the'chain as itappears when laid out flat.-

In the several figures of the drawingV like reference numerals indicatelike parti.` y

The nonskid chain for automobiletires forming the subject matter of thisinvention links `2, 2. coil of wire having about two turns in each coil.locked with'one another as Villustrated in the figures and forin a verypliable pad Ythat will readilyrconform to the curvature and outline ofthe tire when held in place thereon. In interlocking with each other thelinks assume a slightly angular position so thatthey projectfrom thetread of thetire and thus take a firm grip on the i'oad when makingContact with it. f

The pads are fastened together by means 3h yof rubber bands 3, Forthisreason the end of eachpad is provided with a cross bar 4l and the rubberbands pas, around these cross bars between the circular links 2, 2 thusyieldingly connecting tlie pads 1,1 with' one U another. YThe rubberbands are supplenientedfby a pair of chains 5, 5 iii-holding` the padstogether. VThese chains are attached with links 6, 6 to the padel .ateach Y side thereof. Y

'For the purpose of applying and disconnecting the anti-skid chain fromthe tire,

' suitable detachable links 17 7-are placed be- 1 vided with thedetachable links 8, 8.

The rubber bands that connect the pads' l comprises a series of wirepads Lil, eachmade up of a series of interlocking circulai- Each ofthese links comprises ai The links are interwoven'or interl i tween oneof the pads and the rubber bands 3. v In addition to the` detachablelinks i between thev pads l the chains 5, 5 are l with each otherallowthe links of each pad to shift shouldpressure beapplied toV them. Thuswhen the wheell or tire provided with-one of thel nonskid cha-ins isre#l tarded the links of the-pad making contact with the road atthatmoment will be shifted and will cause the links 2, 2 to bunch and form abulge on the pad that will increase the friction between theipad and theroad. I The same is true when the tire rolls around a corner.` Inl thisease the links Von the side ofthe tire will be pushedslightly toward thecenter of the tire and as the re- VV sult of this will bunch up againstthe re-y mainder of the links forming aibulge on the side of the tirethat will increase the Y friction between the chain and the road andprevent skidding when turning a corner.

the tire but the connecting rubber bands between the friction or nonskidpads allow the linkstheieof toA shift and to bunch when re- 75 series oflfriction pads, each of saidy pads ,Y

comprising a series lof circular wire coils interlocked with one another`and held angular to one another, yielding means connecting said padsvto allow the links of said padsfJ to shift and bunch up lwhen the linksare retarded or pressure is vapplied against them. In testimonv whereofI afhx inf/signature.
